How to reconfigure Form Processor Pro v4 form with Form Processor Pro v5?

Please follow this guide to reconfigure your forms from Form Processor Pro v4 to Form Processor Pro v5

Step 1 (Initial Configuration Script):
First of all you need to finish initial configuration script.
Go to http://yoursite.com/fpp/install/index.php where 'fpp' is place where Form Processor Pro is located.
In right upper corner press 'login' enter password admin and finish the script.

Step 2 (Pages):
You need to add <base href="..."> tag directly after <head> tag in your from page.
This line will prevent troubles with images, css and urls that can appear after page processing.
If your page has real URL http://yoursite.com/path/page.html you need to add to page:

<base href="http://yoursite.com/path/">

Second you need to change <form action="..."> path to index.php
of Form Processor Pro v5, instead of previous <form action...>
you need to put:

Put <!-- FPP_ERROR --> into your page, to show there
error about incorrect input, you may insert it in any part of your
where you want user to see error.
You have to do this (action and error) for all pages of the form.

Then you need to name your form. As all configurations will be
stored in one file, Form Processor Pro need to differ them from each
other, to do this you need to add this line just under <form
action...>:

<input type="hidden" name="fpp_form" value="form_name">

where 'form_name' will be name of your form. This line must be added only to the first page of your form.

---optional CAPTCHA---
If you used CAPTCHA in you forms, there ought to be such lines in your page:

where '../fpp/captcha.img.php' is path to captcha.img.php in your Form Processor Pro folder
Also remember name of the next input field, as you later should use it in configuration.

Step 3 (Templates):
In Form Processor Pro v5 you need to use delimiters {# and #}
instead of [ and ], so you need to open your templates in any plain
text editor and change all '[' to '{#' and ']' to '#}' for example your
email template should look like this:

Dear {#firstname#},
Here is information that you had filled in our form:
Name: {#name#}
Company Name: {#company-name#}
Contact Email: {#email#}

Step 4 (config.php):
You need to open config.php that located in main folder of Form
Processor Pro v5 installation in any plain text editor, and add to the
end of this file such line:
[form_name]
this will be the mark where form description is started. You can
use your data from form.cfg, but it should be modified. All lines
that begin with '_error_path=' should be deleted, as errors now showed
on the page where incorrect values were inputted.
First line under form name should be:

page = ../path/formpage.html

Where formpage.html - is first page of your form, path should be relative to config.php, or you can use URL of the page:
